FILTER.

SPECIFICATION forming part of Letters Patent No. 652,966, dated July 3, 1900.

Application filed November 14, 1899. Serial No. 736.984. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM JANDUs, a

citizen of the United States, and a resident 4 form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a side elevation of a battery of my improved filters; Fig. II, an end elevation of the same; Fig. III, an axial section of the filter; Fig. IV, a side View of the filteringbody; Fig. V, a transverse section of the filter; Fig. VI, a view of the central casting of the filter-casing; Figs. VII and VIII, a plan view and a section, respectively, of the packing-gasket; Fig. IX, a section of the waste-water-valve device, showing the collar and the outer casing of the same in section and the ball-cage in elevation; and Fig. X, a section of said device with casing and ballcage in section.

The filter invention forming the subjectmatter of the present application is an improvement upon and development of the filter invention for which application for Letters Patent was filed by me on the 22d day of April, 1899, Serial No. 714,068, and allowed July 17, 1899.

The filter has a cylindrical casin g 1, around the middle of which a ring'2 is secured, preferably by sweating, and which ring has formed upon it, at opposite points, an inletnipple 3 and an outlet-nipple 4, the bores of which correspond to and register with holes in the walls of the tubing forming the casing. The inlet-nipple has an interior screw-thread adapting it for attachment to a bib-cock or other water-fixture. The outlet-nipple is externally threaded for the attachment and adjustment of the waste-valve mechanism or for screwing said outlet-nipple into the inlet of another filter unit, when a number of filter units are used in series to form a battery. The inlet-nipple is screw-threaded to receive the corresponding thread of the outlet nipple of anotherfilter unit. Two flanged heads 5 and 6 fit with their peripheral flanges 7 and 8 over the ends of the casing. One, 5, of said heads has an outlet 9 formed in it for the outlet of filtered water, such outlet extending downward. The inner faces of the heads have central lugs 10, formed with screw-threaded sockets, into which the threaded ends of a stay-bolt 11 fit, so that the heads may be drawn against the ends of the casing. The filtering-body 12 is cylindrical and has annular shoulders 13 at its ends. Said shoulders are as nearly as possible of the same diameter as the inside diameter of the casing. The ends of the filtering-body are beveled at their edges at 1st. The cylindrical body is tubular, and the outer side of the body is formed with ribs 15 or partitions of the same height as the end shoulders and alternately project ing from said shoulders at the opposite ends, so that a shallow tortuous channel is formed around the filtering-body between the latter and the casing. The ends of the windings of said channel are rounded, as shown at 16, so that a free and unobstructed flow is provided for the water in the channel at the bends in the same, and no lodgment for sediment or any solid matter will be found at the bends.

Annular gaskets 17, substantially wedgeshaped in cross-section, arefitted between the bevels of the'filtering-body and the sides of the casing, at the ends of the latter, and are held in the annular grooves formed by said parts by means of the heads, which are clamped to bear against the faces of said gaskets. By this construction of the filter-body and casing and the gaskets and heads onlya very slight annular slit is formed at the end joints, and said slit is closed by the thin edge of the gasket. A very small surface of the joint is exposed to the interior water-pressure in the filter-casing, so that leakage is practically completely avoided. The partitions of the channel are so arranged that one partition will preferably be located across the middle of the inlet-opening, so that the inlet-water will be divided and pass around on opposite sides of the filtering-body through the channels upon the latter. For the purpose of providing a full How of water through the channels on opposite sides of the filtering-body the inlet-opening is of a cross-sectional area at least equal to the cross-sectional area of two of the channels. This will insure a full flow of water through the channels and will insure a sutficient scouring ac tion of the water in the channel when the waste-outlet is opened, as a full flow of water under full pressure will be forced through the channel. A collar 18, having an internal screw-thread, fits upon the outlet-nipple and has a bead at its lower end, over which bead the upper edge of a sheet-metal cage 19 is spun. Said cage is formed from a cupshaped piece of sheet metal cut out to form large lateral openings and a central opening and is spun or otherwise shaped to have its upper portion bear tightly against the end of the collar and around the head of the same. A ball 20 is supported in the cage and may be drawn upward against the end of the waste-outlet to close the same by screwing the collar upward on the outlet-nipple. A nozzle 21 is formed from sheet metal with a slightly-contracted lower end, and said nozzle has its upper end spun or otherwise forced around the bead of the collar and the beaded edge of the cage, and said beaded upper portion of the nozzle is suitably knurled or roughened to form a hold in rotating the nozzle and collar. hen the nozzle is screwed upward on the outlet-nipple, the valve-ball is seated against the end of the waste-outlet, closing the same, and when the nozzle is unscrewed the valve-ball uncovers the outlet and the unfiltered water may flow out around the ball through the openings in the cage and out through the nozzle.

hen the filter is attached to an ordinary water-faucet or bib-cock and the water is turned on, the water will pass around the filtering-body on both sides of the same through the tortuous channel and will be forced through the filtering-body into the central chamber in the latter, from which chamber it will run out through the filtered-water outlet in the head of the casing. When it is desired to draw unfiltered water or to cleanse the filtering-body from accumulated impurities, the waste-valve is opened, as above described, and the water will pass through the tortuous channel, scouring off the impurities by its friction against the surface of the body and carrying them off through the waste-outlet. As the cross-sectional area of the waterinlet is greater than the cross-sectional area of the channels passing to and around both sides of the filtering-body, the resistance in said channels to the passage of the water will cause the water to have a scrubbing action against the surface of the filtering-body when the waste-outlet is open. This same action in the channels will also force the water through the sides of the filtering-body when the waste-outlet is closed and the filtering action takes place within the filter.

When greater capacity is required than the capacity of one filter unit, two or more filter units are arranged in series, as illustrated in Figs. I and II, by screwing the inlet-nipple of another filter unit to the wastenipple of the first filter unit, the waste-valve nozzle and collar being first removed, 850., adding as many units as may be required. For the purpose of providing one common filtered-water outlet from the series or battery of filter units, the head or heads of the added units is or are formed with an opening 22, registering with and connected to the filtered-water outlet of the preceding unit, so that all of the filtered-water outlets discharge in series and out through the outlet of the last unit in the series. In this manner increased capacity is attained, according to the demand, with a filter unit of one size.

The construction of each filter unit insures simplicity and strength. The body of the filter-casing may be made from comparatively-light metal tubing, and the portion of the casing on which transverse strain may come is formed by the central ring, having the nipples formed integral with it and sweated upon the tubing. The endwise strain upon the tubing from the heads and stay-bolt is easily borne and the internal strain of the water-pressure comes against the round sides of the tubing and filtering-body. The only portion exposed to strain from the waterpressure at the ends of the casing is the thin edge of the gasket filling the thin annular slit between the casing and the shoulder of the filtering-body, and such surface is so slight that even considerable strain will not affect it. The filter is easily assembled or taken apart, so that it may be easily constructed and repaired. The ball-Valve provided for the outlet will always present a tight fit, as the ball will be rotated more or less during closing or opening and by the escaping water, so as to present new surfaces to seat against the end of the outlet-nipple. Said ball is preferably made from rubber or similar more or less yielding material.
